Robinhood Chain gas token
On Robinhood Chain, the gas token is ETH: the native currency that every transaction on chain 4663 must spend to pay validators for including and executing the transaction, exactly as defined for any EVM chain. You cannot pay gas in an ERC-20 token; a wallet must hold ETH on chain 4663 before it can swap, approve, or transfer anything.
This is different from "the ETH balance shown on Ethereum mainnet." The gas ETH lives on chain 4663 and is a separate balance. Users typically obtain it by bridging from Ethereum mainnet using the routes documented in the Robinhood Chain docs.

How gas is calculated
Gas is computed as gas_used × gas_price, denominated in ETH, following the standard EVM fee model. Simple transfers use less gas than swaps; swaps that touch multiple pools use more. The final ETH cost fluctuates with network demand.
How to interpret a gas balance
Treat the ETH balance on chain 4663 as your "transaction budget." If it hits zero, every subsequent action fails until you top it up. Wallets that hide network selection can mislead you into thinking you have gas when the balance is actually on a different chain.
Caveats
Bridge fees and time are additional costs to move ETH onto chain 4663 and are not part of gas itself. Nock Terminal does not custody funds; any gas top-up is a normal on-chain transfer or bridge, not a deposit to Nock. Gas price is not a guarantee — actual cost can differ from the wallet estimate.
Concrete example
A user swaps a memecoin on chain 4663 and the wallet estimates ~0.0004 ETH in gas. The wallet holds 0.0003 ETH on chain 4663 and 2 ETH on Ethereum mainnet; the swap fails with insufficient-gas. Bridging 0.01 ETH from mainnet to chain 4663 solves it — the mainnet balance was never usable as gas on 4663.
Frequently asked questions
Can I pay Robinhood Chain gas in a stablecoin? No. Only ETH on chain 4663 is accepted as gas, because ETH is the network's native currency per the Robinhood Chain documentation. Is chain 4663 ETH the same asset as Ethereum mainnet ETH? It represents the same asset economically but is a distinct on-chain balance. You must bridge to hold ETH on chain 4663 for gas. How much ETH should I keep for gas? There is no single number — keep enough for a few swaps plus a buffer. The wallet's gas estimate is a live number, so top up when it is close to zero.
